IDEA - Interferometric Data Evaluation Algorithms

Software for Fringe Analysis and Phase Data Reduction


For over two decades, software for interferometric fringe evaluation has been developed and used at Graz University of Technology throughout several diploma- and PhD-thesis. Funded by the Austrian Science Foundation and the Austrian Ministry for Science and Traffic these Software packages on interferometric fringe evaluation had been subsumed under an MS Windows platform and are made accessible through these web pages.

This Software focuses on subfringe analysis techniques (heterodyne and phase shift analysis, including phase unwrapping) and special subroutines for evaluating path-integrated data (including various Abel-inversion and tomographic algorithms).

Additionally, several tools for data handling, including multiple file operations, filtering, and flexible data visualization, have been included.

This software can be distributed freely (please read the licence agreement) and comes with a manual in postscript fomat.

We also wish to stress that this software was developed by diploma- and doctoral students throughout their course of studies, funded by governmental funding organisations in basic and applied engineering sciences and mechanical engineering. If you are a company or research organisation interested in young men or women experienced in the development of complex software products for experimental data evaluation, please feel free to contact us.
